Tania Cristina Robles and others relax on Pitbull's plane.

Just when it appeared all hope was lost for Puerto Rican cancer patient Tania Cristina Robles, an unlikely hero pulled her from the horror of Hurricane Maria: Mr. Worldwide, aka Pitbull.

Two weeks behind on her treatement for stage 3 brain cancer thanks to the devastating storm that wiped out power across Puerto Rico and shut down hospitals, Robles, 39, couldn’t believe her luck when she was told she could grab a seat on a private charter plane flying from San Juan to Miami on Monday.

Her only clue to the identity of her secret savior was the music she heard when she boarded the plane — one of her favorite Pitbull tunes.

“I said, ‘What are the odds that out of all this, I am having such a great time and they put on the music I always play when I want to be in a happy mood?’” Robles told the Daily News.

Robles, whose 8-year-old twins remained in Puerto Rico, was the only cancer patient on the plane. She was joined by about 15 passengers, including relief workers and a woman traveling with her mother to get treatment for Alzheimer’s disease, she said.

Everyone was shocked when the plane manager let slip the name of their mystery benefactor, Armando Christian Perez, the Miami-born entertainer who has built a global empire as Pitbull.

“I couldn’t believe I was actually on this plane, leaving for treatment. It was a miracle,” Robles said.

Her journey to the U.S. mainland started nearly a month ago, when two different Category 4 hurricanes — Irma and then Maria — laid waste to Puerto Rico.
